Hello,Thank you for the information. I am absolutely certain that the problem is the CCFL lamp. I know about the site www.lcdparts.net - I went there to order a replacement, but I need to know the specific details of the CCFL lamp, i.e. dimensions, type, etc. Without them I cannot make the order. Can you please send me these? Thanks immensely.Miroslav Hrin Hello,Thank you for the information. I am absolutely certain that the problem is the CCFL lamp.

First thing is to check if the video card is OK.
Connect an external monitor to your laptop, if you get a clear image on this monitor then the video card in the laptop is OK.A faulty backlight could be caused by a defective inverter that supplies high voltage to the CCFL lamp or a faulty CCFL lamp. Most likely a faulty CCFL lamp.

The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.Check out www.lcdparts.net for parts, repair service and DIY info.

The length of the CCFL lamp is measured from the left hand edge to the right hand edge of the screen.

You can go to LCD Parts page - Selecting CCFL page where you can also select the CCFL lamp by the laptop manufacturer and model.The length of the CCFL lamp is measured from the left hand edge to the right hand edge of the screen.

Hi.....It would appear your backlight has "blown" (it is just a thin,long bulb in the bottom of your screen)....It will need replacing ....Although you could purchase one yourself to fit it would be best to leave this job to a service engineer
